Impact of COVID-19 Infection During Pregnancy on Newborns and Young Children

Terminated
Conditions
Pregnancy
Covid-19

Other: no intervention
Registration Number
NCT04432779
Lead Sponsor
Centre Hospitalier Universitaire Saint Pierre
Brief Summary

This study aim is to assess impact of COVID-19 infection during pregnancy on outcome of pregnancy, and on developement of the child in early life.

Detailed Description

All pregnant women will be tested for serology during each trimester of pregnancy and at delivery, together with a nasal swab. Children born to women with positive sawb or serology will be followed up for 3 years together with a control child born to negative mother.

In positive mothers, maternal antibodies at delivery will be characterized, placental transfer will be assessed. Persistence of antibodies in children at the age of 1 month and presence of antibodies in breast milk will be measured.

Occurence of premature birth, low birth weight, miscarriage, congenital malformations will be compared in positive and negative mothers. Follow up of children over the first 3 years of life will assess difference in susceptibility to infections and neurological developement in both groups.

GroupInterventionDescription
Women tested positive to SARS-CoV-2 during pregnancyno interventionAll women who had a positive nasal swab or a positive serology during pregnancy or at delivery are included. Follow up end at 1 month post delivery.
Newborns from women tested negativeno interventionNewborns born to mothers who had no COVID-19 infection during pregnancy or at delivery and who consented the follow up study. These control children will be matched with children from the other group for gestational age and ethnicity. Follow up end at 3 years of age.
Women tested negative to SARS-CoV-2 during pregnancyno interventionAll women who had a positive nasal swab or a positive serology during pregnancy or at delivery are included. No follow up after delivery.
Newborns from women tested positiveno interventionNewborns born to mothers who had a positive nasal swab or a positive serology during pregnancy or at delivery and who consented the follow up study. Follow up end at 3 years of age.
Primary Outcome Measures
NameTimeMethod
Outcome of pregnancyUp to the delivery

Incidence of miscarriage, premature delivery, low birth weight, preeclampsia, chorioamnionitis

Secondary Outcome Measures
NameTimeMethod
Prevalence of positive serology to SARS-CoV-2 at deliveryAt the delivery

Measure of antibodies in maternal serum at delivery

Presence of maternal antibodies to SARS-CoV-2 in breast milk in breastfeeding mothersAt 1 month post delivery
To characterize the immunity transmitted to the newborn to cord blood and its persistence at the age of 1 month of lifeUp to 1 month post delivery

Measure of antibodies in cord blood and at the age of 1 month

Clinical evolution of the childrenUp to 3 years

Occurence of infectious disease, neurological development, growth

To characterize placental alterations related to SARS-CoV-2 infectionAt the delivery

Placental histology will be performed in women tested positive for SARS-CoV-2 during pregnancy

Transplacental transfer of antibodies to SARS-CoV-2At the delivery

Measure the ratio of cord blood antibodies on maternal antibodies titers
